METAL CAN, BOX, OR OTHER RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 401,913, dated April23, 1889.

Application filed February 25, 1889.

fication, reference being had to the accompa-.

nying drawings.

The object of this invention is to provide for the opening of a metalcan, box, or other receptacle by tearing out a strip of the metal, ofwhich the can or box itself, or the cover.

thereof, is composed, as distinguished from a strip made of a separatepiece of metal.

Figure 1 in the drawings is a side View of the upper part of acylindrical can or box, illustrating one example of my improvement. Fig.2 is a central vertical section corresponding with Fig. 1. Fig. 3represents a section, on an enlarged scale, of that portion of the canor box which includes my invention. Fig. 4 represents a vertical sectionof part of one side of a can, illustrating another example of myinvention. Fig. 5 is a similar view to Fig. 4, illustrating stillanotherexample.

Similar letters of reference designate corresponding parts in all thefigures.

I will first describe the example shown in Figs. 1, 2, and 3.

A designates the side wall or-body of the can or box, and B the head orcover thereof. The head or cover is represented as overlapping the saidwall or body externally. At a suitable point below the head B there isproduced in the. wall or body A an external depression and acorresponding internal proj ection, I), the said internal projectionpresenting the form of an internal band or fillet. In the margins orcorners of this projecting band or fillet at c 0 there are incisions,which may be made in the metal before it is made up into the can or box,or after the can or box is made or partly made, the said incisionsextending around the body or wall. The said incisions may be of a depthequal to, say, one-half or less of the thicknessof the metal. The widthfierial No. 301,034. (No model.)

of the said band or fillet between the incisions 0 0 may be, say, aboutone-quarter of an inch. From the outer edge, d, of the joint of the wallor body A, in line with the band b, there is provided a projectingtongue, 6.

1n the example illustrated by Fig. 4 the projecting band or filletprojects outward instead of inward. In other respects this example islike that shown in Figs. 1, 2, 3.

In the example shown in Fig. 5 the projecting band or fillet is in thecover B, but in other respects this example is like that shown in Figs.1, 2, 3; and I wish it understood that I consider the cover for the canas constituting part of the can itself, and that the projecting band orfillet if formed on the cover would be within the scope of my invention.

To open the can orbox,the proj ectin-g tongue 6 is taken hold of by handor by any suitable instrument, and by pulling it a portion of the bodyor wall of the can or box is torn out in the form of a strip around thecan or box, thereby separating the upper part of the can or box from thepart below and allowing the said upper part to be removed. to obtainaccess to the contents of the can or box.

The incisions c 0 may be in the inside or outside of the box or can, andmay be on the It is obvious that my invention is as well applicable tocans or boxes of polygonal or WVitnesses:
